History v2: everything — Wallet auto-prompt, age, track replay, share

Adds the deferred pieces from the v1 ship, plus a Mail Share
Extension target so the iOS share sheet picks up flight emails.

Track replay
- `LoggedFlight.icao24` field — populated from FR24 enrichment on
  live-tap adds.
- HistoryDetailView's track query now fires for any flight younger
  than 7 days that has an icao24, pulling the actual flown path
  from OpenSky's /tracks/all endpoint. Falls back to a clean
  great-circle arc otherwise.

Wallet auto-prompt
- RootView subscribes to WalletPassObserver.shared. When the user
  adds a boarding pass to Apple Wallet, the observer's published
  `pendingPass` flips and we present AddFlightView pre-filled with
  the parsed origin / destination / flight # / date.

Airframe age + first-flight date
- `AirframeMetadataService` queries OpenSky's
  /api/metadata/aircraft/icao/{icao24} endpoint. Caches results in
  the existing `AirframeMetadata` SwiftData model so we never
  re-fetch the same airframe twice. (jetphotos and planespotters
  pages are both Cloudflare-gated; OpenSky's metadata API is the
  cleanest free source.)
- HistoryDetailView fires the lookup on appear and persists the
  result; the aircraft card already renders "Age" when a date is
  cached.

Mail Share Extension
- New `FlightsShareExtension` Xcode target (app-extension product
  type) built into the app bundle via an Embed Foundation
  Extensions copy phase.
- `ShareViewController` (SLComposeServiceViewController) parses
  shared text + URLs for flight-shaped codes ("AA 2178"), route
  hints ("DFW → ORD"), and date strings.
- On Save, the extension builds a `flights://import?carrier=…&num=
  …&dep=…&arr=…&date=…` URL and opens it via the responder-chain
  openURL trick (Share Extensions can't access UIApplication
  directly).
- Host app handles the URL via `.onOpenURL` in RootView, switches
  to the History tab and presents AddFlightView prefilled.
- App now has an actual Info.plist (CFBundleURLTypes registered
  for `flights://`); switched from GENERATE_INFOPLIST_FILE to
  INFOPLIST_FILE for the app target.

If the dev portal hasn't registered bundle id
`com.flights.app.share` for the team, the signed archive will
fail. In that case the simpler URL-scheme path still works —
users can hit `flights://import?...` from a Shortcut.
